Agilent Technologies L4400 manual Linking Multiple L4433A Instruments, Mode

5L4433A Dual/Quad 4x8 Reed Matrix

Example: Querying channels for open or close state The following command

returns a 1 (true) or 0 (false) state of channel 204.

ROUTe:CLOSe (@1204)

ROUTe:CLOSe? (@1204) !Returns a 1

ROUTe:OPEN? (@1204) !Returns a 0

Example: Querying the system for module Identify The following command returns the identity of the L4433A:

SYSTem:CTYPe? 1

NOTE	For the L4433A, the query response may include a suffix to indicate
	a 1-wire configuration. For example, the response for the L4433A
	will be either "L4433A" (2-wire mode) or "L4433A-1W" (1-wire
	mode).

Reading Cycle Count and Resetting the Power-On State

Example: Reading the cycle count for a relay The following command returns

the cycle count on channels 304 and 308.

DIAGnostic:RELay:CYCLes? (@1304,1308)

Example: Resetting the power-on state The following command sets the

L4433A to its power- on state.

SYSTem:CPON 1

Linking Multiple L4433A Instruments

You can link multiple L4433A instruments to form a larger matrix. The following two drawings show two- module connections through rows and columns.

You can connect rows in separate instruments using external wiring. Or, using Bank 2 matrices, you can connect through the analog busses. For a clear idea of how matrices are arranged and their connections to the analog busses, see the simplified schematics later in this chapter. You must use external wiring whenever you connect:

•rows in Matrix 1 of separate modules

•rows in Matrix 1 to rows in Matrix 2 on the same or separate modules

•columns of two matrices on the same or separate modules
